Planned for 2013, Intel's 4th Generation Core processors codenamed "Haswell" will be available for desktops, mobile devices and ultrabooks. Preliminary specifications of the Haswell desktop chips have appeared online at the VR-Zone web site, so we take a look.

Intel is expcted to release the Haswell processors for desktops in two phases beginning sometime in early second quarter.

As you see in the table below, the high-end lineup of the Haswell processors for desktops will be the Core i-series 4000-family, consisting of quad and dual-core Core i7 and Core i5 models. They integrate the Intel HD Graphics 4600 core, turbo mode for increased CPU base speeds, Hyper-Threading technology. Other important features include Advanced Vector Extensions 2 or AVX 2.0 as well as AES-NI instructions improvements.

The Haswell processors will also feature dual-channel DDR3/DDR3L memory controllers with DDR power gating support and three PCI Express 3.0 controllers.

The new chips will be built in the LGA1150 package, and will be accompanied by Intel's 8-series "Lynx Point" chipset.
